I have finally got the decomp pin. However the mechanic that works on my bike says its really hard to install and that the whole camshaft needs to come loose. And he is not certain of that it will work out well. So he kinda advises me to not have it installed and just continue without it. Im a bit sceptical to that.

So the question is - should it the decomp pin be replaced/is it neccesary and advisable?

And does the camshaft need to come off to replace this pin?
